The AFPinstall004 is my actual installation, while the other 4 photos are from somebody else's installation - I don't really remember for sure who it was. I think it may have been Dan Checkoway. I used those to help me with mine. Like I said, my flow transducer is wedged in there but I think there are probably better solutions out there. >I was thinking about my valve being installed as yours is - with the addition >of fuel guages on either side of the valve (valve points to the pertinent guage). > > > I think your VM1000 has fuel quantity functions, doesn't it?

I put a bunch of wiring through the spar penetration, too.

After that: Firewall to Mech fuel pump Mech fuel pump to throttle body Throttle body to distribution "spider" "Spider" to cylinders Purge Line: In my picture of the engine installation, you can see the fuel purge line coming off of the valve, going through a grommet in the baffles, and connecting to a bulkhead fitting on the upper/right firewall. From there, the fuel is routed via 1/4" aluminum tubing down the side of the aircraft, right next to the right side fuel vent line. I added another bulkhead fitting next to the fuel vent line fitting in the forward wing root area. From there, a short length of tubing connects that fitting to the fuel tank fitting. The fuel tank just has a simple bulkhead fitting with a short length of tubing inside it that dumps the purge fuel in the second bay of the fuel tank. I wanted the return fuel in the second bay so that the hot fuel doesn't just get immediately pumped out again when doing the purge operation. Purge Cable: You can see that in the picture as well. After going through the baffles, it just goes right through the firewall in a convenient place - it mostly depends on where you want to mount the purge handle on your instrument panel engine control panel.Note the small angle that is bolted to the upper engine. I just used an Adel clamp around the purge cable and bolted to that small angle to secure it. Throttle Cable/Mixture Cable: I'm going to send a couple of separate E-mails with pictures of stuff. The mixture cable is probably the trickiest. I'm told its a real pain for nose-draggers. I had to use the 'one-hole' firewall penetration fitting from aircraft spruce because I needed the cable to penetrate the firewall at an angle. >Additionally, it looks like your purge valve is mounted standing up - mine is >mounted laying down.

Im sure it will come out nice. I still havent painted my 6a and have been thinking about schemes for 3 years while photographing hundreds of them. I finally figured out what made one scheme catch my eye while the other didnt, even though they were very similar. I was speaking with the owner of a 6a at OshKosh last summer and was complimenting him on his paint job. Its a very common 2 tone, white top, red bottom with a couple of stripes separating them mid way through the fuse. He mentioned the trick is to blend the significant color changes with an intermediate color(s). In his case, he had the following: red top, 1/2"black stripe,1/2"grey stripe, then white. I have pictures if you would like. The revealing thing to me is that the plane next to him is red and white with a large gray stripe and doesnt look nearly as good imo. He had a lot of lookers for a simple paint job. Either way, its your baby and you have to paint it the way you like. If you're looking for opinions, I like the fuse striping with no blue and white colors together. One of your last photos shows just red and blue which I think looks good. Good luck.

Having said that I have installed wings on several other aircraft by myself! (alone, solo, etc), including a couple of biplanes. They have their own unique set of problems with flying wires etc. The best method I have found across the board is a single 2X4 with screw in hooks in both ends and a couple of hooks in the ceiling. Simply use a motorcycle tie down at each end of the 2X4 and attach them to the hooks in the ceiling. Lay the wing on the 2X4 about 3/4 of the way out toward the tip. The tie downs can be adjusted up and down independently as necessary. If you place a small piece of carpet on the 2X4 where it contacts the wing that protects the wing also. I have tried the chair and tried saw horses. The motorcycle straps work best for me, but to each their own.

It is a simple platform of maybe 1" thick by 5" wide boards (Asian standard sizes, maybe?) with carpet wrapped around the upper boards, and big casters under each corner. The overall size is something like 16" x 22". You might strap an adjustable plastic sawhorse to one or two of these. I bought the first ones just to get the casters for my wing storage stand. They were less expensive that way than without the wood frame. Terry RV-8A finishing?

You can thank your FAA for that. In order to rebuild and certify aircraft parts the requirements for a shop are intolerable. My cousin would do the best job you could pay for but he would have to completely change his shop setup. The OH shop would have to be contained in it's own separate environment and all parts would have to have cetification and be kept separate from any non-certified parts and hardware - this includes screws, washers, etc. I agree with him that this is too much trouble to go to for a part time activity. Given the necessary changes, etc. it wouldn't pencil out for the consumer. He would have to charge the same as any shop. We haven't even addressed the insurance requirements. Sorry to get your hopes up. On the other hand, if the owner didn't care about an 8313 or whatever it is, it might be a different story. jim ________________________________ Message 8 _____________________________________ Time: 12:42:38 PM PST US From: linn walters Subject: Re: RV-List: overhauling mags --> RV-List message posted by: linn walters This is exactly why you request a 'repair' rather than an overhaul. The manufacturer has a list of items that need to be replaced to meet the 'overhauled' criteria. There is no list for 'repairs' and the shop doing the work has a lot of leeway in what they can do. This is especially important when dealing with certified AC. All the requirements talked about below are tossed out the window when dealing with the Amateur-built experimental classification.

TruTrak does not really characterize it, but I would call it a pseudo attitude indicator with track information. Flying the instrument was interesting. It is quite a bit different than an attitude indicator as it does not indicate actual attitude. The pseudo pitch information is from solid state gyros and rate of climb information. In an high performance airplane like an RV you get much bigger pseudo pitch deflections than you are used to. It looked to me like someone that was not used to flying an attitude indicator in IFC would find this instrument a bit easier as you will hold altitude pretty well if you just line up the level flight balls. For someone really used to an AI I think it would be quite a transition. Long ingrained habits do not work well with this instrument. As in my Dynon EFIS D-10A, things also seem a little delayed and jiggly, compared to actual physical gyros, not really that big a deal. That real downer is that this instrument uses, like the XM antenna in my Garmin 396, a very magnetic GPS antenna. This is completely inappropriate in an aluminum airplane and makes it very difficult to mount the antenna in a position that does not direly affect the magnetic compass. These companies badly need to find a supplier without magnets, for the GA market. By the way, this instrument is a killer substitute for a turn coordinator.

Is there a GOOD reason the front two pipes have to cross over before they go out the cowling? Everyone says that Lycomings have to have an oil cooler because the oil runs hot. Gee I wonder why...two hot exhaust pipes run right past the front of the oil sump and dump gobs of heat into the oil (in addition to the rear cylinders heating up the sides of the sump)!!! So why not trash this exhaust pipe configuration and go to a simple 2 into 1 set up on each side of the engine? Just bring the two pipes together off the same side and dump it out the cowling without crossing over in front of the oil pan. A Lancair 360 builder I know built his own exhaust like this from Aircraft Spruce parts. He says the crossover setup actually creates back pressure that robs engine power. Airplane isn't flying yet but I certainly see his logic in doing it. Another Q200 builder did the same thing with his 0-200 Continental engine and says there has been a noticeable difference in under-cowl temps (and no engine performance degradation). I can't believe this hasn't come up before, anybody know the answer? What wives-tail or urban legend says the exhaust has to crossover? Is this another thing we builders do just because production aircraft did it and because everyone else does it? Larry Vetterman why aren't you building NON-crossover exhaust?
